form an array of sqrt of float numbers from another float array by using accelerate vs forloop way

accelerate.m

#import <Foundation/Foundation.h>
#import <Accelerate/Accelerate.h>

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        NSLog(@"start");
        int count = 10000000;
        float *x = malloc(count * sizeof(float));
        float initial = 0;
        float increment = drand48()*count;
        vDSP_vramp(&initial, &increment, x, 1, count);
        
        float *y = malloc(count * sizeof(float));
        vvsqrtf(&*y, x, &count);
        NSLog(@"number x: %f", x[100]);
        NSLog(@"number y: %f", y[100]);
        NSLog(@"end");
    }
    return 0;
}
